Research

Overview

Research group: York Plasma Institute

Research interests

  • Theory and simulations of non-classical transport effects in inertial confinement fusion plasmas; considering, in particular, the role of non-locality and inverse bremsstrahlung in the presence of magnetic fields.  The development of reduced non-local models for inclusion in radiation hydrodynamics codes and benchmarking these reduced models with kinetic simulations.
  • Relativistic electron beam propagation and collimation in laser-produced plasmas.  Investigation of self-collimation and novel collimation schemes relevant to fast-ignition inertial confinement fusion.
  • Quantum electrodynamic (QED) plasmas produced by ultra-high intensity lasers.  The development of a kinetic theory to describe such plasmas and the use of this theory to describe basic QED-plasma phenomena such as the absorption of electromagnetic waves.

Projects

Laser absorption to gamma-ray photons and electron-positron pairs in laser-produced QED plasmas, kinetic modelling of ICF plasmas.
